This document contains the recommended practices for the traceability of civil aircraft life-limited parts (LLPs) applicable to landing gears. A unified means of tracking flight cycles, flight hours, and calendar time is provided, which will ease the interchange of parts between companies and through the component’s life cycle. A harmonized means of defining “back-to-birth” (BtB) traceability is provided to ensure airworthiness of service LLPs.
